Ba xr6t

[DVS JEZ]

Hey guys,
Have a BA XR6T auto I have installed id1000's, valve springs and fuel pump. Tuned up fine however when sitting in Park or neutral the fuel trims start climbing till they max out then throws up an P0171 too lean bank 1, P1131 P1132 02 lean and rich errors (I have changed 02 sensor and these 2 haven't come back up), P2105 P2110 throttle actuator control system forced shutdown etc.

I am going to try another throttle body tomorrow to eliminate it.

The car drives and boosts perfectly, can sit idling in gear for as long as you want trimming 5% stft but when selecting park or neutral and idling the trim starts climbing to +30's and then throws the error.

Has anyone had this issue?

Thanks
Jez

You need to scale the injectors correctly

This was my thoughts at first. However it doesn't make sense that idling in gear is trimming stft perfectly and off boost and on boost are exactly as commanded.

I will recheck my calculations

Sounds more like you have the Offset wrong (too small). Are these the numbers you had:

Voltage drop due to rpm drop or similar? Possible Incorrect voltage offset?

I thought you tuned with sct Jez
